Abstract

A process for manufacturing connecting rods is provided which comprises the steps of compacting, sintering, and powder forging a powder metal comprising a carbon source and a prealloyed powder consisting essentially of iron and copper. The connecting rods made from this process have sufficient hardness and strength to be used in an engine and do not require any additional quenching or tempering.
